[X2Go-User] How to run a script that needs a terminal initially but is then a GUI (as a single application)?

I discovered x2go a year or so ago and I'm finding it very useful, thank you! :-)

I'm running x2go client on an xubuntu 19.04 system and the server on an xubuntu 19.10 system.

I have a short script on the server system which first runs encfs to create a file system and it then runs a GUI that uses the file system just created. How can I run this as a 'Single application' in x2go?

The script is called 'digimax', I have tried running a terminal as the single application by putting the following command into x2go:-

xfce4-terminal -x /home/chris/bin/digimax

This successfully asks for the encfs password in the terminal window that appears but it then just disappears and no GUI app follows. The script /home/chris/bin/digimax works perfectly when run locally in a terminal window.

Is there any way I can get x2go to run this for me as a single application?
